Tess Holliday is never one to shy away from posing nude, but the size 22 model's latest topless shot may be one of her raciest photos yet.

The 32-year-old took to Instagram on Wednesday to share a stunning black and white portrait of herself wearing nothing but a chest harness that left her bare breasts exposed.

When captioning the BDSM-inspired snapshot, Tess opted for an alien emoji, and many of her 1.5 million followers loved the sultry new look.

Candid: Tess recently admitted that she hasn't been sharing selfies because she doesn't like the way she looks in them, but she posted this snapshot to reminder herself that she's a 'babe'

'I literally was just looking up where to find harnesses for thicc girls like me,' one person wrote, while another added: 'You look like a dominatrix, which is a pretty cool look.'

A few days before, Tess posted a picture of herself wearing a crochet top over a black tank and leggings, explaining that she might be sharing a racier image of herself donning just the see-through top.

'Nick said he wants to photograph me naked and this top, & y’all know I’m always down for noodz, but until then here is a photo of me in it not nood,' she wrote.

Although she proudly shows off her curves on her Instagram page, she is also candid about her insecurities.

Hitting back: The size 22 model said she hates when people assume she has 'lost weight,' explaining: 'I’m still fat as hell, but I know my angles AND I still look good'

Last week she posted a selfie while admitting that she has been struggling with her self-image.

'I haven't posted a selfie in so long, mostly because every time I go to take one I hate how I look. (I know that sounds silly, but it’s very real),' she explained. 'So I’m posting this for myself as a reminder that I’m a babe.'

In the photo, Tess is lying on a bed wearing an off-the shoulder bodysuit that laces up the front. She is wearing the same cream rib knit bodysuit in a series of images she posted earlier this month.

The pictures show her posing seductively on a bed, and while sharing them, she had some choice words for people who assume she has slimmed down.

'I hate when ppl comment "you’ve lost weight, you look good!" No b**h, I’m still fat as hell, but I know my angles AND I still look good,' Tess captioned the images.

In one of the snapshots, Tess is posed on her knees and leaning forward to show off her décolletage.

Her long auburn hair is tossed over one shoulder, and she is giving the camera a come hither stare in one photo. The other shows her looking away from the camera, as she leans down toward the bed.

Tess posed for the images when she was in London for the Cosmopolitan UK Self Made summit in which she was the keynote speaker.

A few days after posting the pictures, Tess and her husband were back in Los Angeles to attend the premiere of Amy Schumer's new movie 'I Feel Pretty.'

The film is about an insecure woman who suddenly thinks she is the most beautiful woman in the world after following a head injury.
